That is correct, in this case. Now, we have the case of the chosen disciples of the Apostles in the NT, who we consider to have had Apostolic authority passed on to them. How many of them were witnesses to Jesus? How many were not?
They were not disciples of the apostles but of Christ and they didn’t have the same authority as the apostles.
Very few of the disciples would’ve been eye witnesses of Jesus, but to be counted as one of the twelve one did as did Matthias.
